7.3.5.6 Overtemperature Protection

The TPS92610-Q1 device monitors device junction temperature. When the junction temperature reaches thermal shutdown threshold T(TSD), the output shuts down. Once the junction temperature falls below T(TSD) – T(TSD_HYS), the device resumes normal operation. During overtemperature protection, the FAULT bus is pulled low.
